Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

This paper describes the use of inductive loop technology to present a larger magnetic/metallic profile to a vehicle detection loop embedded in a roadway. Motorcycles and high-axle vehicles like delivery trucks present a small if non-existent profile to most vehicle detection loops. An electronic device is powered by the vehicle battery and is attached to a vehicle undercarriage. It produces a magnetic field that influences the frequency of the embedded vehicle loop presenting a larger vehicle profile to the loop and triggers the associated logic to alter a traffic signal, open a gate, or indicate the presence of a vehicle.

Introduction

Vehicles undetected by detection loops may result in loss of revenue to businesses like parking facilities. If the vehicle is not detected at the entrance to a parking structure, a driver may choose to park elsewhere. Likewise, an undetected vehicle at a traffic intersection poses a safety risk to the driver and other drivers as the driver may become impatient and choose to not wait for a green light to be triggered. Also, waiting for traffic signals may impact traffic flow and reduce driver satisfaction. This paper describes a device and technique to detect low metal profile vehicles, which assists with traffic flow and has the potential to save lives.

Implementation

The device "amplifies" the metal footprint of a vehicle so as to be detected by buried t...
